It is a precision adjustable (both tilt-able for angle adjustment and rotatable), highly compact and solid lockable optical mount that reliably carries and optical element (e.g. a mirror, prism, lens, wave-plate, filter and the like) so that a plurality of such optical mounts can be arranged into a compact and optical efficient system.

2. Description of Related Arts

Referring to FIG. 2 of the drawings, an adjustable/non-adjustable precision optical mount 100 is disclosed which includes a generally stationary plate 200, an external-spherical round shaped optical element carrier plate 300 (aka An optical element carrier plate 300 having an external spherical shaped surface along its circumference 326), a generally movable plate 400, and a locking ring 500. The optical element carrier plate 300, fitting in and mating with in the space adjustable combined internal-spherical shaped cavity that is formed by the stationary plate 200 and the movable plate 400 forms a ball joint mechanism. The external-spherical round shaped optical element carrier plate 300 can be tilted for angle adjustment and rotated for rotation adjustment. The locking ring 500 can push the movable plate 400 to adjust the space adjustable combined internal-spherical shaped cavity to lock the external-spherical round shaped optical element carrier plate 300 and therefore to firmly lock the optical element that is carried thereby.

Referring to FIG. 1 of the drawings, conventional optical mounts 001 are known, which include a generally solid, rectangular backup support plate 010 and a rectangular faceplate 014. The backup plate 010 and faceplate 014 are coupled in facing spacing alignment with one another. A series of springs 016, ball 012 and screws 020 maintains space and couples alignment of the backup plate 010 and faceplate 014. The faceplate 014 carries and optical element 026 (e.g. a minor) and is adapted to be moved by means of rotate-able knobs 028 having threaded shafts 018 that extend through the backup plate 010 to be advanced into contact with faceplate 014 and thereby impart an angle tilting or translational movement to the faceplate 014 so that the position of the optical element 026 may be correspondingly changed relative to an incident beam of optical energy.

Conventional optical element mounts, such as those typically associated with optical components are generally not suitable to position optical elements utilized in like Laser applications. Typically, conventional adjustable optical elements mounts are suspended from a base structure by a system of screw jacks and springs.

Conventional optical mounts, and optical elements, are normally affixed to a plate that is suspended from and movable with respect to a backup support plate firmly mounted to an optical bench. If the optical mount setup is in a laser system, laser beams are generally arranged substantially horizontally, and therefore the optical element surface is typically perpendicular to gravitational force. Thus, the optical elements are cantilevered from the surface of a support backup plate and must rigidly support a relatively heavy weight suspended wherefrom.

Conventional optical mounts for adjustment with tilting and rotating are separately operated by two different mechanisms. Combining the two different mechanisms together can operate both tilting and rotating adjustment; the complicated mechanism occupies more space and lowers the reliability.

A series of springs in conventional mounts between the ridged support plate and the moveable plate from which the optical element (e.g. a mirror) is mounted provides a force that maintains one or more optical elements actuators and compression or tension, thereby stabilizing the optical element. However, conventional type spiral springs have little or no resistance to shear forces, which are large and heavy optical elements cantilevered from the rigid mount. Therefore, pins or ball type sockets are generally required to support the moveable plate. These supporting devices introduce frictional hysteresis that inherently reduces the required position accuracy of the optical elements.

Further, where screw type actuation is manually or mechanically manipulated to position the optical elements, some type of locking mechanism is required. During activation of the locking mechanism positioning errors may be introduced. For example, the simple procedure of tightening a setscrew to lock an optical element requires much tedious and time-consuming trail and error to align one or more mirrors to a desired setting.

Additionally, for example a laser, the efficiency of a laser is critically dependent on the angular alignment of the optical components defining the laser resonator. Mechanical vibrations and ambient temperature changes unavoidably transmitted o the optical mount assemblies jeopardize the mirror alignment of a field laser system.

There is a need for an optical element mount assembly that provides precision alignment and adjustment of an optical element. Further, there is a need for an optical element mount assembly where vibration, shock and changes in temperature minimally affect the alignment of the optical elements. It would be desirable to provide an optical element mount assembly, with adjustment feature as a function mechanism that is removable as the optical element mount is adjusted and the optical element mount totally is finally set to reduce the affect from vibration, shock and temperature change and to reduce mechanical hysteresis applied to any threaded screws.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide an optical mount assembly, which can eliminate the aforesaid disadvantages of known designs, and other problems found within the prior art, for a wide variety of optical devices.

Another object of the present invention is to provide an optical mount assembly, which the optical element can be angle adjusted or stay tilted in any direction and rotated around the axis with specific tooling.

According to a first embodiment of the invention, a precision optical mount is disclosed having a generally stationary plate with a partial-spherical shaped hole, a generally movable plate with a partial-spherical shaped hole, an external-spherical round shaped optical element carrier plate and a locking ring. By means of a pair of guiding mechanisms, the partial-spherical hole of the stationary plate is coupled in spacing and facing relationship and co-axis adjustment with the partial-spherical hole of the movable plate forms a space adjustable combined internal-spherical shaped cavity. The external-spherical round shaped optical element carrier plate mates with and fits in the space adjustable combined internal-spherical shaped cavity to form a ball joint mechanism. The locking ring screw-threads in the threaded hole of the stationary plate to push and move the movable plate. Thus the space adjustable combined internal-spherical shaped cavity is adjusted and the external-spherical round shaped optical element carrier plate is locked and therefore the optical element that has been carried thereby is locked.

According to a second embodiment of the invention, a precision optical mount is disclosed having a generally stationary plate with a conical shaped hole, a generally movable plate with a conical shaped hole, an external-spherical round shaped optical element carrier plate and a locking ring. By means of a pair of guiding mechanisms, the conical shaped hole of stationary plate is coupled in spacing and facing relationship, and co-axis alignment with the conical shaped hole of the movable plate forms a space adjustable combined internal-conical cavity. The external-spherical round shaped optical element carrier plate mates with and fits in the space adjustable combined internal-conical cavity to form a ball joint mechanism. The locking ring screw-threads in the threaded hole of the stationary plate to push and move the movable plate. Thus, the space adjustable combined internal-conical cavity is adjusted and the external-spherical round shaped optical element carrier plate is locked and therefore the optical element that has been carried thereby is locked.

According to a third embodiment of the invention, a precision optical mount is disclosed having a generally stationary plate with a partial-spherical shaped hole, a generally movable plate with a partial-spherical shaped hole, and chamfered edge cylinder shaped optical element carrier plate (aka an external-round column circumference and chamfered edges optical element carrier plate and a locking ring). By means of a pair of guiding mechanisms, the partial-spherical hole of stationary plate is coupled in spacing and facing relationship, and co-axis alignment, with the partial-spherical hole of the movable plate to form a space adjustable combined internal-spherical shaped cavity. An external-round column circumference and chamfered edges optical element carrier plate mates with and fits in the space adjustable combined internal-spherical shaped cavity that forms an angle tilt-able and around the axis rotatable joint pair mechanism. The locking ring screw-threads in the threaded hole of the stationary plate to push and move the movable plate. Thus, the space adjustable combined internal-spherical shaped cavity is adjusted and the external-round column circumference and chamfered edges optical element carrier plate are locked and therefore the optical element that has been carried thereby is locked.

Advantages of these optical mounts according to the present invention include the aspect that an external-spherical round shaped optical element carrier plate, which is constituted by a precision-machined external-spherical shape and relative optical element carrier interface adapt, or external-round column circumference and chamfered edges optical element carrier plate, which is constituted by precision-machined external-round column circumference and chamfered edges and relative optical element carrier interface adapt, and the aspect that a space adjustable combined internal-spherical shaped cavity is formed by a movable plate, which is constituted by a precision machined partial-spherical shaped hole, and a stationary plate, which is constituted by a precision machined partial-spherical shaped hole, or a space adjustable combined internal-conical shaped cavity which is formed by a movable plate, which is constituted by a precision machined conical shaped hole, and a stationary plate, which is constituted by a precision machined conical shaped hole. It is necessary that any spring and/or ball for suspension are superfluous for a highly accurately position, high precision, high stability and highly reproducible optical mount. A specially designed angle adjustable (or say tilt-able) and rotation around axis implement mechanism can be attached onto and removed from the optical element mount, so any threaded screws and springs for adjustment are not needed.

Another advantage of the present invention is that the gravity center of optical element is overlapped or close to the support centre to eliminate cantilever structure that the weight, vibration and shock will cause torsion and instability. Another advantage of the present invention is the locking mechanism, which will keep the optical element in an accurate position and not be affected by shock, vibration and temperature change. Also, this locking mechanism will not cause any stress on the optical element. Another advantage of the present invention is that it has a very simple assembly structure for operating and maintenance.

The FIG. 10 shows a space adjustable combined conical cavity 251, which is an adjustable space cavity having a conical shape which is formed from a combined or composite construction. Spacing facing co-axis alignment base 236 of conical hole 210 of stationary plate 201 and the base 426 of conical hole 410 of movable plate 401 together form this space adjustable combined internal-conical cavity 251.

The external-spherical round shaped optical element carrier plate 300 can be tilted for angle adjustment around the center 350 (FIG. 11) of the external-spherical round shaped optical element carrier plate 300 and the optical element 624 that is carried thereby is tilted for angle adjustment. Around the axis 352 (FIG. 11) of external-spherical round shaped optical element carrier plate 300, the external-spherical round shaped optical element carrier plate 300 can be rotated and the optical element 624 that is carried thereby is rotated for adjustment.

The Adjustable/Non-adjustable Precision Optical Mounts 102 according to a third embodiment of the present invention is disclosed while referring concurrently to FIGS. 6-7 and 12-13 of the drawings. The optical mount 102 has a stationary plate 200, a movable plate 400, an external-round column circumference and chamfered edges optical element carrier plate 301 (best shown in FIG. 13) and a locking ring 500.

The description of space adjustable combined internal-spherical cavity 250 references are in paragraph [0041] above.

FIG. 12 shows that the external-round column circumference and chamfered edges optical element carrier plate 301 mates with and fits in the space adjustable combined internal-spherical cavity 250 (FIG. 7) to form a tiltable feature for angle adjustment around the axis rotatable joint pair mechanism 272. The external-round column circumference and chamfered edges optical element carrier plate 301 can be tilted for angle adjustment around the center of the space adjustable combined internal-spherical cavity 250 and the optical element 624 that is carried thereby is tilted for angle adjustment. Around the axis 353 of external-round column circumference and chamfered edges optical element carrier plate 301, the external-round column circumference and chamfered edges optical element carrier plate 301 can be rotated and the optical element 624 that is carried thereby is rotated.

FIGS. 14 and 15 show an example of the angle adjustment approach. A removable angle adjustment tool implement 700 includes tilting plate 716, binding plug 714, and actuators 750 which constitutes with super fine screw sets 708 for adjustment and spring plungers 712 for keeping position. The tilting plate 716 is put on the back-end surface 345 of the external-spherical round shaped optical element carrier plate 300. Binding plug 714 through the hole 718 on the tilting plate 716 plugs into the interface 360 of the external-spherical round shaped optical element carrier plate 300 and binds the tilting plate 716 tightly onto the external-spherical round shaped optical element carrier plate 300. The actuators 750 are installed to the relative thread holes 722 & 724 on four corners 720 of the tilting plate 716. By adjusting the super fine adjustment screw sets 708 to import the angle adjustment movement, the tilting plate 716 can be tilted for adjustment and therefore the angle adjustment movement is transferred to the external-spherical round shaped optical element carrier plate 300. The optical element 624 that is carried thereby is angle adjusted for optical energy beam alignment. When completing the angle adjustment alignment, one uses a torque wrench to turn the locking ring 500 to push the movable plate 400 to adjust the space adjustable combined internal-spherical cavity 250 to lock the external-spherical round shaped optical element carrier plate 300, so that the optical element 624 that is carried thereby is firmly locked and fixed. Disassemble the binding plug 714 and remove the removable angle adjustment tool implement 700.

FIGS. 16 and 17 show an example of the rotating and angle adjustment approach. To rotate and tilt the external-spherical round shaped optical element carrier plate 300 (FIG. 2) around the optical path axis 351, one must rotate and tilt the optical element 624 (such as wave-plate, nonlinear crystal, prism, etc.) for adjustment; and for that a removable rotating-tilting tool implement 800 that constitutes a worm driven continuous rotation mechanism is necessary. The removable rotating-tilting implement 800 is being bonded to the optical mount 100 with a binding plug 830. The rotational movement output port 836 of the removable rotating-tilting implement 800 contacts the back-end surface 345 (FIG. 11) of the external-spherical round shaped optical element carrier plate 300, the mating pins 826 insert into both mating holes 330 on the back-end surface 345 of the external-spherical round shaped optical element carrier plate 300 and the mating holes 840 on the output port surface 845 of the removable rotating-tilting movement implement 800. Super fine adjustment screw sets 810 and spring plungers 816 constitute actuators 820. One installs the actuators 820 into the relative holes on the corners 850 of the removable rotating-titling movement implement 800. It is shown in FIG. 16 that rotation input knob 822 joins with the worm shaft of the removable rotating-titling movement implement 800. So when rotating the rotation input knob 822, the external-spherical round shaped optical element carrier plate 300 will be rotated for adjustment. One adjusts the fine screw knob 810 of the actuators 820 of the removable rotating-titling movement implement 800 which can be tilted and therefore the optical element 624 that is carried thereby is tilted. When completing the rotating and tilting alignment, a torque wrench is used to turn the locking ring 500, to push the movable plate 400, to adjust the space adjustable combined internal-spherical cavity 250, to lock the external-spherical round shaped optical element carrier plate 300. Therefore the optical element 624 that is carried thereby is firmly locked and fixed. One disassembles the binding plug 830 and removes the removable rotation-tilting movement implement 800.
